PAPER BOX.

SPECIFiCATION forming part of Letters Patent No. 595,684, dated December 14, 1897.

' Application filed June 3,1397. Serial No.639,2o5. (Nomodel.)

object being to provide an improved knock-- down box of this class having peculiar folding features, wherebythe *end portions are firmly interlocked and the outer end fiap has its entire surface clear forprinting thereon'; and the invention consists in the' peculiar arrangement and manner of folding the several parts of the box and of interlockin g the same, all as hereinafter fully described, and more particularly pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective view illustrating a paper-box blank in a partly-folded condition containing my improvements. Fig. 2 is a perspective view illustrating my im proved box having one end partially folded, the top sections opened outwardly, and the other end of the box completely folded and locked, but showing the locked fiaps only partially folded inwardly. Fig. 3 is a plan View of the paper blank from which the box is made.

Referring to the drawings, 3 indicates the bottom section of the box-blank; 4' 4, the two side sections; 5 and 6, the cover-sections; 15, a tongue on section 5; 9 and 90,the main fiaps of each end of the box; 13 13 and 14, the three triangular parts of each end; 10. 10, inwardly-folding end fiaps; 12 12, hook-bearing end'fiaps, and'x x hooks thereon.

Lines 09 (between the blank parts 5 and 10 10 'and 6 and 12 12) indicate cuts which to the extent of such lines separate said parts, so that they are free for folding.

The dotted lines c on the blank indicate the usual indented folding-lines, and the lines b b between the sections 90 and 9, at each end of the bottom section 3, are preferably partly cut through the paper,so that the said triangular parts 13 and 14 may, without inconvenience, be folded, as indicated at the partly-folded end of the box in'Figs. 1 and 2. The said cover-section 6 is provided with a slit 7, which receives the tongue 15 on sec tion 5 when the two cover-sections are closed over the box.

The blank, Fig. 3, is folded to produce the paper box and certain parts thereof interlocked, as follows: The four end fiaps 12, 90, 9, and lO (shown at the upper end of Fig. 1) are folded upwardly at right angles to the bottom and side sections 3 4 4, bringing the upper corners of the triangular parts 13 13 one back of the other, as there shown, and the said four 'sections are then moved in the directions indicated by the three arrows in said figure. Said end fiaps 12 and 10 are gradually brought to the relative positions shown at'the upper end of Fig. 2, and still swinging the said sections toward each other the end fiaps 12 and lO and main fiaps 90 and 9 are brought side by side into coinciding positions at the end of the box with the said folded triangular parts 13 13 and 14, projecting fromthe junction of the main fiaps 9 and 90,with the bottom section 3 inwardly, as partially shownin Fig, 2. The section 9 thus placed forms solely the outer. end part of the box, upon which any required printing may be effected before the blank is folded. The free ends of the end fiaps 12 and 10 are next interconnected by passing the hookx through the slit 8 in the end fiap 10, thus forming the end of the box, which thus far consists of two thicknesses of material, and providing such a connection of said four end fiaps of the box as serves to retain the side sections 4 of the box in proper positions at right angles to the bottom section 3. The said two interlocked end fiaps 12 and 10 are then bent or folded inwardly (as partly indicated on the lower end of the box in Fig. 2) closely against the inner side of the main fiap 90, the extremities of the end fiaps 12 and lO being thus brought to bear against the upper side of said triangular sections 13 13 and holding the latter against the bottom of the box, finally producing the end of the box, consisting of four thicknesses of paper.

The above-described manner of forming the ends of the box is the production of a plain outer surface on each constituted by the entire main fiap 9. This provides a clear end surface on which to print, as indicated in Fig. 0

IOO

any desired letters or characters descriptive of the contents of the box, Which printing may be done before folding the blank into box form.

The cover of the box comprises the section G, having the slit 7 and substantially of the width and length of the open side of the box, and the section 5, folding partly over said section G, having the tongue for engagement in said slit 7, thereby suitably uniting said cover-sections, whereby they are retained in closed positionsj Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

, 1. A blank for a paper box, comprising a bottom and two side sections, and two interengaging cover-sections, and parts for each end of the box comprising three triangular sections at the end of the bottom section, two rectangular end fiaps, one at the end of each side section, an infolding reetangular section on the end of one of the said end flaps having a hook-receiving slit therein, and a hookbearing end flap on the end of the second of said end flaps, said hook being thus located' for engagement in said slit, whereby the end fiaps are held side by side in coinciding positions, to the end that said hook and slit containing sections may be folded against the inner side of the end of the boX, substantially as described.

2. A blank for a paper box, comprising a bottom and two side sections, and two interengagin g cover-sections, and parts for each end of the box comprising three triangular sections at the end of the bottom section, two rcctan gular end fiaps, one at the end of each side section, an infolding rectangular section on the end of one of said end flaps having a hook-receiving slit therein, and a hook-bearing end flap on the end of the second of said end flaps, said hook being thus located for engagement in said slit, whereby the end fiaps are held side by side in coinciding positions, to the end that'the main fiap 9 of the blank shall solely constitute the outer sides of the ends of the box, thereby providing a clear face for printing thereon, and that said hook and slit containing sections may be folded against the inner side of the end of the box, substantially as described.
